I attached a rebased patch-set.

Also, I made the folowing changes from the previous.

1. Fix to not use a new deptye

In the previous patch, we introduced a new deptye 'm' into pg_depend.
This deptype was used for looking for IVM triggers to be removed at
REFRESH WITH NO DATA. However, we decided to not use it for reducing
unnecessary change in the core code. Currently, the trigger name and
dependent objclass are used at that time instead of it.

As a result, the number of patches are reduced to nine from ten.

2. Bump the version numbers in psql and pg_dump

This feature's target is PG 16 now.
